Even more recently, the adaptor was knocked loose on the corner of the desk and the power pin broke completely. I researched and assumed it was the same common problem and came across this site. Apply some fresh solder on contacts. While heating one of the contacts, remove the solder from this contact using the desoldering pump. So, you can do that, Cathy. The offical Toshiba fix is to do this and then run a bead of hot melt glue around the connector.

Tried this on my A70 and it worked! What am I doing wrong? This is the second time I tried to fix this. I cr4990 the sony vaio vgn cr490 problem. Hi there, thanks for the advice.
